Effects of alumina surrounding in sintering process on ZnO-Bi<inf>2</inf>O<inf>3</inf>varistors doped with CoO

Nonlinear current-voltage properties of zinc oxide-bismuth oxide varistors doped with cobalt oxide were investigated. The composition of ZnO doped with 0.5 mol% Bi2O3and 0.75 mol%CoO was prepared and sintered in two different surroundings, zinc oxide-bismuth oxide-cobalt oxide powder and alumina pow...
